There may be just one man whose name flashes across your computer screen more than President Obama's and that's John McAfee's -- whose anti-virus software is probably protecting the very machine you are reading this on.

McAfee just lowered the price on his Molokai, Hawaii, home to $3.7 million from $4.9 million. The four-bedroom, five-bathroom newly constructed 5,796-square-foot house sits on 5.3 ocean-front acres. The 1,262-square-foot master suite includes a floor-to-ceiling Molokai rock fireplace and entertainment center. The master bathroom has a large Jacuzzi tub with ocean views, a glass block shower, his and her sinks and a hickory-lined linen closet; there's also a 528-square-foot covered deck off the master suite with ocean views.

The ocean-view great room has sliding glass doors that open onto a covered deck. The gourmet kitchen has top-of-the-line stainless steel appliances and custom granite countertops. The floors are of cumaru Brazilian teak, Italian porcelain tile and bamboo.

The property, in the Popuhaku area, is entered through a 20-foot-tall Japanese gate house, "guarded" by Afghan teak horses. The perimeter fence includes Molokai rock columns and tight cedar panels. A large circular driveway winds through Kiawe forest into the 1,600-square-foot porte-cochere.

British-born McAfee was the first to distribute anti-virus software using the shareware model. He also is considered a pioneer of instant messaging. His company, McAfee Software Inc., went public in 1992, and he is the author of books on computer viruses and yoga.

He is based in Rodeo, N.M., where he built a villa in the midst of his private airstrips from which he pursues the sport of aerotrekking (ultra-light planes).
